This is interesting but of course completely unreliable: it will break
with any item going over the treble clef (e.g. a \tempo or a \mark).

This works out perfectly, thank you.

I had already figured that out before you replied. Unfortunately this
doesn't work out if you for example want to have the time signature
printed at every staff group. However, I found the way to do it: wrap
the context mod in a function, remove all time signatures by default and
apply the function to whichever staff should print the time signature.
See the attached files..
